PURPOSE:To achieve good conductive connection between annular contacts by using a ring having slit and a relatively thin wall portion opposite the slit, thereby causing the ring to elastically deform so that the ring an absorb the step in the hole diameter of the annular contacts when the ring is inserted into a through-hole. CONSTITUTION:A ring 1 has two protruding parts 4 for circuit conduction which are symmetrically formed at an angle of 180 degrees on both sides of a slit 3 of the ring 1. In the inner surface portion of the ring intermediately of the circumference connecting both protruding parts 4, in other words, in the inner surface portion of the ring which is facing (directly opposed to) the slit 3 extending in the axial direction of the ring 1 at an angle of 180 degrees, the ring 1 has a belt-like longitudinal groove 6 extending in the axial direction, the wall thickness of which is thinner than the remaining ring portion. For this, both side portions in the longitudinal direction (axial direction) of the ring can reduce the diameter independently of each other. (figuratively speaking, it can elastically deform in the shape of a trumpet), so that the ring 1 is put in good contact and engagement with corresponding contacts. |
